Small Aquarium Heater with LED Display for 25-50 Gallon Tanks

Focusing on providing functional yet great-valued aquarium supplies, hygger continues to release users from the chore of maintenance and caring for beloved pets. From the brand's previous page, the products highlighted include hygger Lights, hygger Top Sales, Aquarium Cleaning Tools, and Aquarium Heaters.

The hygger submersible fish tank heater features an explosion-proof quartz glass and a high-temperature resistant nickel-chromium heating wire that work together to distribute heat quickly and efficiently, creating a comfortable aquatic environment for your fish. This aquarium heater also boasts an adjustable LED digital controller that displays real-time water temperature and the set temperature. The built-in temperature probe allows for temperature adjustments from 59°F to 93°F (15°C to 34°C), with a preset to prevent excessively high-temperature settings. Pressing and holding the button for 5 seconds changes the readout from Fahrenheit to Celsius.

The PC plastic guard of the heater has high-temperature resistance and protects your fish from getting burnt. The hang hole on the controller makes it convenient to hang the unit up, and the two strong suction cups allow for easy mounting of the heating element to the tank wall.

The heater offers multiple functions, including temperature setting memory, running-dry protection, and overheating protection. When the water temperature exceeds 95°F, the heater will automatically stop working, sound an HH error code alarm, and turn the blue light on. To resolve this, the user should unplug the heater and wait for the heating rod to cool down to normal temperature.

The dry run shut-off protection feature ensures that when the heating rod is exposed to air, the heater will stop working, sound an E1 error code alarm, and turn the blue light on. In this case, the user should unplug the heater and fully submerge the heating rod in water.

Important tips for using the aquarium heater include: 1) Always unplug the heater before performing water changes and plug it back in when it is fully submerged; 2) Allow the heater to cool for at least 15 minutes before removing it from the aquarium; 3) Ensure the heater rod does not touch the sand or gravel on the tank bottom, as the heat difference may crack the heater glass; 4) Keep the heater fully submerged underwater at least 5 inches at all times, as the plastic guard will melt if the heater is exposed to air during heating or cooling; 5) Maintain water circulation for better heat distribution; and 6) Position the heater close to the tank filter to avoid overheating and ensure better performance.

The hygger submersible fish tank heater is available in various wattages suitable for different aquarium sizes, from 10 to 190 gallons of marine and freshwater tanks.
